Sarah has two tests at school next week, a math test and a physics test. Let A represent the event that she passes her math test and B represent the event that she passes her physics test. If A and B are independent events with P(A)=0.30 and P(A AND B)=0.21, find P(B)

P(B)=0.7

Step-by-step explanation:

When the events do not affect each other, they are known as independent events. In other words, two events are independent if the outcome of the second event is not affected by the outcome of the first event.

If A and B are independent events, the probability that both events will occur is the product of the probabilities that the individual events will occur:

P(A and B)= P(A)*P(B)

In this case, P(A and B)= 0.21 and P(A)= 0.30

Replacing:

0.21=0.30*P(B)

Solving:

0.7=P(B)

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
